SPARKARRESTER AND QNSu E SPECIFICATION forming pa f Let e ate t No. 2 9 dared Q ebe 8 1- pplication filed March 18, 1881. (No model.)

To all whom it may concern: Be it known that I, ALFRED BERNEY, a citizen of the United States, residing at Boston, in the county of Sufiolk and State of Mas-- sachusetts, have invented certain new and useful Improvements in Spark-Consumers with Straight Stacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others 1o skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and 'to letters or figures of reference marked thereon, which form a part of this specification. I

15 My invention relates to that class of spark arresters and consumers in which the sparks,

' cinders, and unconsumed products of combustion are deflected and returned to the furdescribed hereinafter, reference being had to the accompanying drawings and letters of reference marked thereon.

In the drawings, Figure I is a longitudinal vertical section of alocomotive-boiler with my improvement attached. Fig. II is a vertical cross-section on line w x.

In the drawings, A is a part of the shell of a locomotive-boiler, having the usual fines, B, smoke-arch O, and chimney or stack D. This stack is bolted to the saddle E, consisting of the lower part or base, a, the middle part, b, and the upper part, c. The upper part is of peculiar construction, having an annular flange, d, to which the barrel of the stackis secured, a curved outer part with flange d, to which the part bis bolted, and an annular curved lip, c, projecting downward, to which theliftpipe F, made of wire-gauze or perforated sheet metal, is attached by a metal ring, h. This lift-pipe passes to the bottom of the smokearch, and is there secured to aering,f. The exhaust-tips G are arranged inside of this lift-pipe, and to .them a number of beveled rings, 9, are attached, between the lower edge of each one of which is left a small space, so

dotted lines.

that the air can pass up between them and assist in creating a draft. An inner barrel, H,

is connected to the lower part, a, of the saddle, which is provided with inclined guides 'i, by which the sparks, &c., are conveyed into the connecting-pipes I, which connect with the return-fines K, and convey the sparks, &c.,

to the furnace, where they are consumed. A steam-jet pipe, 70, provided with a suitable stop-cock, k, forces the sparks, &c., through the said return-fines into the furnace.

The rings 9 may be extended to the upper part of the lift-pipe, if desired, so as to form a free and unobstructed exhaust, as shown by The operation is as follows The sparks, 850., which pass through the tubes B are forced up through the inner barrel, H, by the exhaustblast, and are deflected by the curved lip of the upper part, c, and passing through the space formed between the barrel and the middle part, b, of the saddle, are guided into the connecting-pipes I, and from there are forced through the return-fines K, by means of a steam-jet from pipe k, into the furnace, where 7 5 they are consumed. The smoke can pass up through the meshes or perforations of theliftpipe F, and, with the exhaust-steam, freely into the atmosphere.

The advantages of this construction of sad. 8o

dle are that the part 0 can easily be removed at any time, when worn out, and replaced by a new one, as it will be more apt to wear out than the barrel or other parts of the stack. The lift-pipe being extended and connected to 5 the curved lip of the upper part of the saddle, and being arranged around the outside of the exhaust-tip, allows a much better and freer draft, and at the same time prevents the possibility of sparks, &c., passing out of the stack, 9 while the smoke and exhaust-steam pass into the atmosphere.

Having thus desc 1 claim is- 1. In a spark-arrester, a. saddle, E, provided with a detachable part, 0, having an inner curved lip, arranged substantially as specified.

2. Ida spark-arrester, a .saddle, E, consisting of a base, a, a middle part,*b, and an up- 10 bed my invention, what per part, 0, provided with a curved hp, 0, all arranged substantially as shown and described.

3. In a spark-arrester, a saddle, E, consisting of a base, a, a middle part, b, and an upper part, 0, provided with a curved lip, e, in combination with a perforated lift-pipe, F, arranged outside of the exhaust-tips, substantially as shown and specified.

4. In a spark-arrester, the combination, with the exhausttips Gr, ofa series of beveled rings, g, and a perforated lift-pipe, F, and a saddle, E, constructed and arranged substantially as set forth.

5. In a spark -arrester, a saddle, E, construoted substantially as shown, with a liftpipe, F, exhaust-tips G, rings g, connecting-
